Spark Plugs

Just finished putting the W-2 heads on the 360. I have a question on what is the best spark plug to run with my combo. I should have about 10 to 1 compression. Its a .060 360 with W-2 heads. Mopar 284/480 cam. Running a MSD ignition box, and coil. What is the best plug and what gap should I run. Thanks RIck
